If your hard drives are in
“Normal” (JBOD) mode, then
the Drive Select button lets
you choose which of the 4
separate drives will be seen as
the primary drive by your PC.
If you are using a USB
connection with JBOD mode,
then you will still be able to see
all four separate hard drives in
My Computer. If you are using
an eSATA interface to connect
Quattro only one single drive
will be active in this mode.
Use the Drive Select button
to chose which drive will be
active in this case.

If four separate drives are not desired, use RAID 0, RAID 1, or RAID
5 instead of “Normal” (JBOD) mode. You may switch between RAID
modes with the RAID utility during installation. The utility may also be
installed or run from your DriveNavigator CD.
If you’ve changed the Quattro’s RAID mode to normal (JBOD) mode
with the RAID setting utility, disconnect the Quattro from the computer.
Hold the Select button for three seconds or until the Power LED is lit
orange and beeps. Click the Select button again to change which single
drive is activated. You can see which drive is selected by its Access
LED.
Here’s what the LED colors mean:
Green: Selected and activated.
Orange: Not selected but activated. If you are using a USB
connection the drive will still be visable in My Computer. With an
eSATA connection, only the selected drive will be usable.
Off: Not selected and invisible to your PC.
If you are in a RAID mode where the four drives appear as a single
drive, such as RAID 0, 1, or 5, then the Drive Select button is disabled.
